Inductors: Energy Storage Applications and Safety Hazards
The inductor subdues any output current fluctuations by changing its behavior between a load and a supply based on the SMPS current ripple. The inductor behaves like a load and stores energy to prevent ripples from producing excess current. It acts like a current supply when the ripple reduces the current value.
